The service life of bimetallic cylinder liners is mainly determined by the following factors:

1. Material and processing quality. Including materials and heat treatment, good mechanical properties and comprehensive properties such as wear resistance and corrosion resistance are the basic guarantees for improving service life.
2. The manufacturing process has a significant impact on the surface and internal quality, and incorrect clamping, grinding, or cutting operations can cause scratches and other defects on the surface of the parts; Therefore, choosing a suitable manufacturer can increase its usage time.
3. The size of the clearance also affects the sealing performance of the piston ring, which in turn affects the stability of the engine and prolongs the wear rate of the cylinder wall. Therefore, controlling product quality is also one of the methods to improve the time inside the bimetallic cylinder set.
4. Whether the daily maintenance and upkeep work is in place also directly affects its service life.
Taking into account the above aspects comprehensively can better ensure the durability of the double layered steel ring during use and effectively extend its service life.
